- Features of organisms.
- Features in the cells of all living organisms.
- Cytoplasm, Cell membrane, DNA as genetic material, Ribosomes for protein synthesis, Enzymes involved in respiration.
- Main features used to place organisms into one of the five kingdoms.
- Animals
- -Cells don't have cell walls. -Multicellular and feed on other organisms.
- Plants
- -Cells have a cellulose wall. -They are multicellular. -Plants make their own food by photosynthesis.
- Fungus
- -Cell wall not made of cellulose. -Unicellular or multicellular. -Feed on dead organic matter or parasites.
- Prokaryote
- -Unicellular. -Cell wall not made of cellulose. -No true nucleus.
- Protoctist
- -Unicellular with a nucleus.
